Re: Date Field Printing

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

There is actually no *NULL value for any field, it is something
you can check for to see if the value should be considered null, but
the field will always contain some data (even though it may be bad
data, as in decimal data errors for numeric).

Also, date fields are not yet *NULL capable.  So we don't even
have something we can check to see if it's null or not.  But, regardless,
checking for *LOVAL is exactly the same as checking for *NULL
as far as I can tell, as long as *LOVAL is not an allowable entry.

I have not actually used NULLs in RPG myself, but this is how I've
heard they work.  Please correct me if I am wrong.

Regards,

Jim Langston
